Amazon web services 弹性豆茎芹菜酱和容器

我试图在Elastic Beanstalk上运行芹菜节拍，但它在自动缩放时会在所有实例上运行，这会导致重复周期性任务。我找到了一个解决方案，其中包括标记leader实例，并仅在该实例上运行芹菜节拍主管流程，但它对我不起作用

这是我的

.ebextensions/program.config中的代码

        docker exec `docker ps --no-trunc -q | head -n 1` cp /srv/supervisor-app-beat.conf /etc/supervisor/conf.d/supervisor-app-beat.conf

      docker exec --privileged -d `docker ps --no-trunc -q | head -n 1` killall -q supervisord

container_commands:
  01_mark_lead:
    command: "touch /tmp/leader_only"
    leader_only: true

并且命令
01\u mark\u lead
成功运行，如日志
/var/log/cfn init cmd.log

但是，当我尝试检查容器时，我没有看到创建的
leader\u
文件或启动了节拍过程，我做错了什么？
随着时间的推移，leader可能会改变，因此我不确定这是否是最佳方法。但对于您的特定问题，我会尝试将命令更改为
命令：“touch/tmp/leader\u only&&ls-l/tmp”
，以查看文件是否在运行时创建。如果是的话，那么很可能是某个地方删除了它。
